How to find the surface area of Rectangular Prisms:
Find the area of two sides (Length*Height)*2 sides;Find the area of adjacent sides (Width*Height)*2 sides;
Find the area of ends (Length*Width)*2 ends;
Add the three areas together to find the surface areais .
The surface area of a rectangular prism is 8*6 + 6*4 + 8*4 = 48 + 24 + 32 = 72 + 32 = 104 yd2.
The correct answer is A.
SA=2(LW+LH+WH)
L=8
W=6
H=4
SA=2(8*6+8*4+6*4)
SA=2(48+32+24)
SA=2(104)
SA=208 yd^2
answer is D
L=8
W=6
H=4
SA=2(8*6+8*4+6*4)
SA=2(48+32+24)
SA=2(104)
SA=208 yd^2
answer is D
